Plan dual TUI/CLI mode for Kotlin Clikt+Mordant CLI app
Takeaway: Next time I'd point it straight at the relevant cliApp source files and skill docs up front instead of letting it rediscover the whole module structure from scratch.

kotlin multiplatform sessions with coding agents
14 sessions on kotlin multiplatform with a coding agent: the agent failed at least once in 8, and 6 finished without a human stepping in.
Clean rebuild iOS app and commit iOS-only fixes
Takeaway: I'd start by pointing the agent straight at the maestro run-ios-local.sh script and the simctl UDID lookup instead of letting it explore the repo structure first, since that's what it ended up using anyway.
Fix iOS simulator watchdog crash in iCloud backup transport (Kotlin Multiplatform)
Takeaway: Next time I'd point straight at the ICloudBackupTransport file since the crash log made the source pretty obvious, and let the agent confirm the main-thread-blocking theory with a quick web search before touching code.
Boot and run iOS + watchOS TwoFac app on paired simulators
Takeaway: Next time I'd point the agent straight at the .xcodeproj instead of the .xcworkspace, since the workspace-based xcodebuild -list call just errored out and wasted a step.
Revamp test suite across Kotlin Multiplatform apps (CLI, Compose, watch, sharedLib)
Takeaway: Next time I'd ask for the parallel sub-agent model to be verified up front, since the first run wasted a cycle on a 404 for a non-existent model name.
Revamp test suite for TwoFac (Kotlin Multiplatform) with parallel sub-agents
Takeaway: Next time I'd skip trying to bootstrap the messenger/sub-agent planner up front and just have the agent start reviewing and committing test changes directly, since the planner kept failing or reporting 'no plan found' and ate most of the session.
Merge origin/main into Kotlin Multiplatform branch, resolve conflicts favoring branch
Takeaway: Next time I'd ask upfront to run a quick build after each individual conflict resolution instead of one big build at the end — the ICloudBackupTransport and TwoFacLib merges needed several reset/re-merge cycles to untangle because the failures surfaced too late and mixed together.
Parallelize 4 code-simplification plans across subagents (Kotlin Multiplatform)
Takeaway: I'd start by pre-registering the correct subagent name ('worker') in the prompt so I don't waste a round-trip hitting an 'Unknown agent' error before it even starts.
Audit KMP codebase for bloat via parallel subagents
Takeaway: I'd tell it up front which files/paths are likely stale so it doesn't waste turns hitting ENOENT on renamed importer adapters and onboarding files — that was the main friction.
Document google-cloud-credentials file locations in AGENTS.md
Takeaway: Next time I'd just ask upfront for a complete search across all source sets (android, ios, desktop) instead of finding the desktopMain file in a follow-up prompt.
Add cross-platform folder/file picker for local backup export in Kotlin Multiplatform
Takeaway: Next time I'd just say upfront that the picker needs to work on Android, iOS and Web too, not just desktop — that would have saved a whole extra research and implementation pass.
Fix cancellation bug and build backup Phase 1 policy in Kotlin Multiplatform lib
Takeaway: I'd start the next session by pointing straight at the plan file and the exact behavior I want (like I did with the CancellationException bug report), since giving the agent the precise symptom and fix upfront meant it found the bug fast and fixed it correctly first try.
Refactor single-transport backup into multi-provider registry (Kotlin Multiplatform)
Takeaway: I'd start by naming the provider metadata type up front (BackupProvider, not BackupProviderInfo) so I wouldn't need a follow-up rename pass across sharedLib, composeApp and cliApp plus a second commit and ABI re-check.
